Presentations

In this talk Tiago Teles takes apart password protection scheme analyzing the attack
resistance of hashes, hmacs, adaptive hashes (such as script), and encryption
schemes. First, we present a threat model for password storage. Then audience
members will learn the construction, performance, and protective properties of these
primitives. Discussion of the primitives will be from a critical perspective modeled as
an iterative secure design session.
Ultimately, this session presents the solution and code donated as part of the on-
going OWASP PSM (password storage module) project. Discussion of this solution
will include key techniques for hardening PSM learned through years of delivering
production JavaEE code to customers...

Neutralizing Peer-to-Peer Botnets

By Dennis Andriesse.

This presentation is a case study on our takedown efforts against state-of-the-art peer-to-peer botnets.
Unlike conventional botnets, peer-to-peer botnets are decentralized, and thus cannot be disabled by neutralizing centralized control facilities. Takedowns against peer-to-peer botnets require a highly decentralized approach targeting the infected drones themselves. We describe the technical and ethical challenges we faced in our own takedown attempts.
